Why Jams Are Almost Universally Permitted
Jams, jellies, and preserves combine high sugar, high acidity (pH below 4.6), and low water activity. This combination inhibits pathogen growth, making them shelf-stable. They are permitted under cottage food law in virtually all 50 states.
Almost Always Permitted
- Fruit jams — strawberry, peach, blueberry, raspberry, fig, muscadine, apple
- Jellies — grape, apple, crabapple, mint, jalapeño jelly
- Preserves and marmalade — citrus marmalade, chunky fruit preserves
- Fruit butters — apple butter, peach butter, pumpkin butter (shelf-stable versions)
Gray Areas and Not Permitted
- Lemon curd — contains eggs and butter; most states classify as TCS
- Low-acid vegetable spreads — tomato jam without added acid, onion marmalade
- Fresh salsa — requires refrigeration; not cottage food
- Dairy-based spreads — cream cheese blends, dulce de leche
Jalapeño Jelly
Jalapeño jelly (peppers + apple juice + sugar + vinegar + pectin) is permitted virtually everywhere. The vinegar and sugar drive pH well below 4.6, making it shelf-stable despite the pepper content.
Labeling Jams
Standard cottage food label fields apply plus net weight in oz and grams. Most fruit jams have no major allergens — confirm with each ingredient supplier, as some pectins contain trace ingredients.
